What is the connection between malignant neoplasms and crabs?

The more common term for malignant neoplasms, cancer, is Latin for crab, and the word "carcinogen," meaning a cancer-causing agent, comes from the Greek word for crab, "karkinos." What is the connection between these two seemingly unrelated things?

Cancer, both the disease and the astronomical constellation, derive from the Latin cancer or cancrum, meaning crab. The astrological sign, of course, is said to resemble a crab and the disease was so named by the ancient Greek physician Galen (129-200 A.D.) who noted the similarity between a certain type of tumor with a crab as well—the swollen veins around the tumor resembling the legs of a crab.

Old English adopted cancer directly from Latin and used it for a variety of spreading sores and ulcers. This early sense survives in the modern word canker. From c.1000 in a manuscript called Læce Boc (Leech Book), collected in Oswald Cockayne’s Leechdoms, Wortcunning, and Starcraft of Early England, Vol. II, 1865:

Gemeng wið þam dustum, clæm on ðone cancer.
(Mix with the dust, smear on the cancer.)

And from Wyclif’s 2 Timothy, 1382:

The word of hem crepith as a kankir

The word was being applied specifically to the disease we today call cancer by the beginning of the 17th century. From Philemon Holland’s translation of Pliny’s Historie of the World:

Cancer is a swelling or sore comming of melancholy bloud, about which the veins appeare of a blacke or swert colour, spread in manner of a Creifish clees.

The astronomical sense of cancer is from the Latin name for the constellation of the crab. The name was known to the Anglo-Saxons, but only as a Latin name and was not assimilated into English until the Middle English period. It appears in Ælfric’s De Temporibus Anni, written c.993, in a list of the constellations of the Zodiac:

Feorða • Cancer • þæt is Crabba
(Fourth, Cancer, that is the crab.)

The Anglicized name appears c.1391 in Chaucer’s Treatise on the Astrolabe:

In this heved of cancer is the grettist declinacioun northward of the sonne...this signe of cancre is clepid the tropik of Somer.
(At this first point (head) of cancer is the greatest declination northward of the sun…this sign of cancer is named the tropic of summer.)

How long are jaw alignment braces needed for?

I recently got told to wear removable jaw alignment braces, which are the ones with big blocks on them. They cause my jaw and face to really ache, and look hideous as they're very big and bulky. Does anyone know how long I will have these for before getting fitted braces?
I'm 17 in 2 weeks, and all I want is to hurry up and get fixed braces, but my orthodontist never tells me anything.

it all depends on how badly crooked your teeth are. you may have them for weeks, months or longer. it just all depends on how your teeth were before.
and your orthodontist probably doesn't tell you anything because they never know anything for sure. something could always change and you wouldn't wanna be let down, would you? mine did the same thing. lol.  (+ info)

What is the largest angle a human jaw can exhibit without unhinging?

i think it's 45 degrees but is there a world record? Also I wonder if fixed jaw ratios are genetic, gender-specific, or all-around the same. It seems that everyone should physically be able to open their jaws to the max but some people with big mouths have trouble opening their jaws.

I think it's 45 degrees too, you're right. I bet if you stretched your jaw a lot then it could probably start to go farther.  (+ info)

What home remedies are there for a locked jaw?

For a few years, I've had a misaligned jaw and the left side cracked when I opened my mouth really wide. But for the past 2 weeks, the right side of my jaw has just gotten locked and I can't open my mouth completely without pain.

I have read a lot about TMJ and people often advise seeing a dentist or chiropractor, but I was wondering whether anybody has any home remedies I can try first. I have tried massaging and putting a heating towel. Although the heating towel allowed me to open my mouth wider, it still didn't cure the problem.

Also, I tend to sleep with my mouth open and I consistently sleep sideways, which I believe is what caused my misaligned jaw after years and years.

Any advice on what I can do as a last resort before seeking professional help??


See if you can find someone who knows the "KI Method". It is kind of like a massage, but focuses on the points of your body that need healing.  (+ info)

When i eat anything my right jaw will start to hurt?

I woke up this morning and ate an apple and this extreme pain into my jaw. The pain is nothing like i have ever felt before. I can not eat anything without having this massive pain. Once i have no food in my mouth i feel nothing. What is wrong with my jaw?

Sounds like TMJ (temporomandibular joint) syndrome.  (+ info)

How can I stop waking with jaw tension and headaches each morning?

I wake with a tense jaw and a dull headache (sometimes a migraine) every morning and have done for quite some time now. I've been thoroughly checked out medically and although I'm told I have nothing serious wrong there is no explanation of why I am feeling like crap every day. I've recently read about TMJD or TMD and have been given a night guard by my denist to try to stop possible jaw clenching. I've only had the guard for about a week but things have not improved - I think they have got worse.
Can anyone else with similar problems tell me how they have gained their life back? My quality of life has gone and I'm sick of having my days ruined.

Get your doctor to order a "sleep study".
I had similar experiences like yours, waking with headaches, jaw pain, etc., woke up feeling like I was having a hang-over.
They found I had developed "sleep apnea".
One stops breathing several times during the night, causing oxygen levels to drop, restless motion during sleep, adding to the lack of restful sleep.
If you do find that sleep apnea is a factor to your condition, they will prescribe a "CPAP" machine.
This helps you to continuous breathing during the night.
The reason many feel like crap that have sleep apnea and don't know it, is because your body is trying to wake you, to start "breathing".
Hope this helps, and best of results to your cure,

What causes my jaw to hurt when I sleep?

I've never had sleeping problems, especially with my jaw, and I have woken up the past 3 days and the right side of my jaw is KILLING ME! Throughout the day, the pain starts going away, but I'm not sure what it is. My parents say it might be TMJ, and I've never been known to grind my teeth or lock my jaw while I sleep. Anyone else have any suggestions?

ITs like the way you sleep. It happened to my neck before. Sorry but you'll just have to wait... it goes away.
now mine

How long after corrective jaw surgery can you start talking?

I work at home (technical rep) and I am trying to find a good time to schedule my jaw surgery. Anyone that has had the procedure done..how long can you start speaking? I'm not worried about how I will look, because I will be at home most of the time, but when can you start opening your mouth and hold a normal conversation? Thanks!

It depends if they wire your jaws shut or not. I would not plan to do the type of work you do if they wire your jaws shut for about 4 weeks. If not wired shut (though I think generally this does not get as good of results and there is risk for greater complications), I think you're probably looking at 1-2 weeks of not being able to talk a lot.

(When you say "jaw surgery", I assume you are referring to changing of bones in your face that would change your profile, bite, etc.)  (+ info)

What would make your jaw bone start making a "popping" sound when you try to open your mouth?

Like when you go and try to eat something, you open your mouth to eat and "pop"! Your jaw pops likes its going out of socket.

TMJ-Temporalrmandibular jaw joint syndrome. It's the joint connecting the upper and lower jaw. It gets out of place. It can make it difficult to open your mouth very wide and can cause pain into the ear. Warm packs can help. So can a dentist or chiropractor. If you clench your teeth or grind them in your sleep it could cause it. You might need a mouth guard to wear at night. You can try to help it back in place yourself by closing your mouth gently. Then take your thumb, putting it into your mouth between your teeth and cheek. Place the tip of your thumb into the space behind your last tooth and the joint.With a little pressure, press into the joint. Repeat that a few times and it might help it back in place.  (+ info)

What are some liqueified recipes for someone has their jaw wired shut?

My boyfriend broke his jaw a few weeks ago and now has to have his jaw wired shut for 6 weeks. He is starving and has lost a lot of weight. I need some liquefied recipes please.

Protein mixes added to fruit and veggie smoothies will help the most. I don't think he would want liquefied meat (yuk).
You can get them at health food stores. Those are what I would try.  (+ info)
